I've observed something quite strange on my StackOverflow account reputation. At beginning of this month my reputation was 2,315. Then one day suddenly it's downed to 2,289. Assuming that someone played around and I didn't consider it. There was reputation log (-2) on many of my posts. However, in the next several days, my reputation was downed to 2,263 but there is no reputation log; including all above reputation log.
(call this First Event)
First: 2,315 -> Down w/ Log (-26): 2,289 -> Continuous Down w/ All Log Removed: (-26, the same number): 2,263.
(this is Second Event)
But from this morning til mid-day: First: 2,263 -> Down w/ Log (-16): 2,247 -> Up w/ All Log Removed: (+16): 2,263.
I'm wondering about this strange behaviors. Any explanation? Thanks!
